I have an idea. Can we assume that although every country measures cases and deaths differently, they generally use the same rubric on a day to day basis? I think we can (when they don't the absolute numbers jerk around like they have done a couple of times in France and once in China). Let us assume so for he moment. We can then calculate the ratio of cases to deaths in each country. These numbers will all be different. In themselves they don't mean anything much, and are not comparable between nations to any great deegree. However these numbers will stay constant if the rate of new cases matches the rate of deaths.
Consequently, it is reasonable to deduce that the rate of new cases will match the rate of deaths if we are in steady state, or plateau; the ratio (let's call it my statistic) will be constant in a country. Thus if we look at the difference in this statistic from one day to the next the difference should be zero if we are at plateau. Before we reach plateau the rate of increase of new cases will be greater than the rate of increase in deaths so the difference between consecutive days (monday minus Tuesday, say) will be positive. When we are over the plateau the rate of increase of deaths will exceed the rate of increase of deaths and my statitsic will go negative.
What I have found is this all hangs together. My statistic has been falling from positive values in every country higher up the cases table on a day to day basis for a couple of weeks, and in the last couple of days the daily differences have reached zero, and even gone negative in some countries. I have been posting the data.
So there is no need to look at absolute cases and absolute deaths. I doubt we will have a real clue about absolute numbers for months, if ever for some countries. But we can look at ratios and their trends and I think this is giving the clearest picture of what is happening worldwide i terms of predicting increases in cases, plateau and downturn.
At present there is clear evidence of downturn, started or about to start, worldwide. What we don't know yet is if this will sustain or bottom out. My statistic may detect early signs, though. Actually, let's not use English understantement and fake vagueness, the statistic will detect this.
I have every confidence in your statistical analysis and the trends it is showing. (It's why I keep on wondering about this seasonal aspect, even though we are told it isn't). What I am saying is that you can't compare one countries figures with another as we have no idea of there methods of acquiring those figures. Although I agree that if those methods are consistent, the analysis of them is consistent and an excellent basis for analysis, and in turn, for making decisions.
All I am interested in, is what the accurate fatality figure is in the UK. The reason I started looking for the true figure was because, two weeks ago, the ONS actually published a fatality figure from over a week before, that was significantly in excess of the figure announced by the Government that day. (A similar situation to this week when the Government announced a daily figure, and on the same day, published that we had passed that figure two weeks ago).
Bit of a dog with a stick, but since I can now calculate the deaths with what I believe to be a very high degree of accuracy, I have been. I believe this figure is important to the UK decision making process, together with the trend analysis that you are reporting.
*edit*
If they add new deaths but not new cases this will make our cases to deaths ratio suddenly become smaller. If they add new cases from the care homes it should stay the same. I have a feeling they will count as new cases only those cases that resulted in deaths which is incorrect. My guess is we won't see a massive change in the ratio of cases to deaths.
Well one of us is going to have to rework some numbers and my bet is it won't be you.
*further edit*
Really excellent and thanks. I think everyone should bear that in mind, particularly when emoting about possible numbers. We need to be patient and then, eventually, we will have a clear picture. I am not aiming that comment at [MENTION=396]WATFORD zero[/MENTION] btw who is applying a scientific view, but at some posters who start to froth at the mouth a little and lose sight of objectivity.
Thank you. I try
(and holding 3 way conversations on a forum is hard work)
